Fix slow Wi-Fi yourself.
12 steps, ~45 minutes.
Most "slow internet" is fixable for free. This is the exact checklist Kareem runs before any service call — placement, mesh sizing, throttle detection, and how to kill that monthly router rental forever.

1
Speed test from the source
Plug a laptop directly into the modem with an ethernet cable. Go to fast.com or speedtest.net. This is the actual speed your ISP is delivering — the upper limit of what Wi-Fi could ever match.
What to do with the number
If you're paying for 300 Mbps and getting 280, your ISP is honest. If you're paying for 1 Gbps and getting 220, your modem can't handle the speed (most ISP modems are 5 years out of date). Call retention — they'll usually swap it free.

Speed test from every room
Walk a phone or laptop to every room you actually use. Run the same speed test on Wi-Fi. Write down each room's download speed. This map is your dead-zone diagnosis.
What "good" looks like
If you get ≥ 60% of your wired speed everywhere, your network is fine and the problem is somewhere else (device, app, ISP throttle). If you get < 30% in 2+ rooms, you have a coverage problem — jump to Step 7.
Most routers end up shoved in a closet, behind a TV, on the floor, or inside a cabinet. Walls and metal kill Wi-Fi. The router needs to be central, elevated, and out in the open.
The 3-rule placement test
1) Central to your home's footprint (literally find the middle and put the router as close as possible). 2) Off the floor — eye level or higher. 3) At least 3 feet from microwaves, baby monitors, and big metal objects. Just moving the router can add 30% coverage.

Restart in the right order
The classic IT fix — but it has an order. Unplug modem AND router. Wait 60 seconds. Plug modem in first. Wait until ALL its lights are solid. THEN plug in the router. Wait 2 minutes. Test.
Why the order matters
The router needs the modem to be ready before it asks for an IP. If you boot them together, the router sometimes gets a "limited" connection that survives until the next restart. Clean boot = clean session.
Log into your router admin (usually 192.168.1.1 or 192.168.0.1 in a browser). Find the firmware page. Click "check for updates." If your router hasn't updated in 6+ months, this often fixes random disconnects and crashes.
Forgot the password?
Most router admin defaults are printed on a sticker on the router itself. If someone changed it, a factory-reset (hold the recessed button 10 seconds) wipes everything — you'll have to reconfigure Wi-Fi name + password but you'll get back in.
6
Separate your bands (2.4 vs 5 GHz)
Most routers ship with one Wi-Fi name that broadcasts on both 2.4 GHz (slow, long-range) and 5 GHz (fast, short-range). Your devices guess which to use — and often guess wrong. Split them into two separate networks with different names.
Naming convention that works
"MyWiFi" for 5 GHz (use this for phones, laptops, TVs in nearby rooms) and "MyWiFi-Long" for 2.4 GHz (use this for the back-yard camera, the garage smart lock, the printer that lives down the hall). You control which devices use which band — you stop guessing.
7
Diagnose the dead-zone pattern
Pull out your room-by-room speed map from Step 2. Three patterns predict three different fixes:
Pattern → Solution
One specific room is weak: A Wi-Fi extender ($30–80) plugged in halfway between the router and that room solves it. Cheap, works fine for one trouble spot.
An entire floor or half the house is weak: You need a mesh network. One router is not enough. See Step 8.
Speeds drop only at certain times: ISP throttling or neighborhood congestion. Skip to Step 10.

Size a mesh system correctly
If you need mesh, here's the rule that most people get wrong: one mesh node per ~1,500 sq ft, ONE FLOOR. Two floors? Double it.
What to actually buy (no affiliate links here)
1,500 sq ft single-floor: 1-pack — sometimes just a better single router fixes you.
1,500–3,000 sq ft OR multi-floor: 2-pack mesh.
3,000+ sq ft multi-floor: 3-pack mesh.
Honest brand list (all priced $200–$500 for 2-packs): Eero (Amazon-owned, ridiculously easy setup), TP-Link Deco, Netgear Orbi, Asus ZenWiFi. Avoid: anything "Wi-Fi 5" still on sale — only buy Wi-Fi 6 or Wi-Fi 6E. The price difference is gone.
~$200–$500 once · fixes coverage forever
This is the most universally-missed save. Your ISP charges $14–18/month to rent you a router. Over 3 years that's $504–$648. A perfectly good router (or mesh system from Step 8) you OWN costs $80–$200 once.
How to return it
Call ISP support, say: "I'm using my own router/modem and want to stop the equipment rental." They'll either send you a return kit (UPS sticker, drop at any UPS Store) or tell you to drop it at a local store. Get a receipt for the return. If they don't remove the rental charge within one billing cycle, call retention and dispute it — quote the return receipt.
$168–$216/year recovered · forever
If your speeds are great at 10 AM and terrible at 8 PM, it's probably neighborhood congestion (cable modems share bandwidth across the block). If specific services are slow at all times (Netflix is fine, YouTube buffers), it's application-level throttling.
The 2-test diagnosis
1) Run a speed test with a VPN on (NordVPN, ExpressVPN free trial works). If your speed JUMPS, your ISP was throttling.
2) Test at 10 AM, 6 PM, and 10 PM over two days. If you see a U-shaped drop at peak hours, it's neighborhood congestion. Fiber is the only true fix — AT&T Fiber, Frontier Fiber, or Google Fiber if available.

Audit what's on your network
Log into your router admin and look at the connected-devices list. Most households have 15–40 devices on Wi-Fi: phones, laptops, TVs, speakers, smart locks, doorbells, fridges, thermostats, security cameras. Some are bandwidth hogs you forgot existed.
The 3 biggest hogs
4K security cameras: can upload 5–10 Mbps each, 24/7. If you have 4 of them, that's 40 Mbps just leaving your house.
Cloud backup: Backblaze, iCloud, Google Photos — they sync constantly. Schedule them for off-hours.
Smart TVs with auto-play previews: Roku and Apple TV preview videos on the home screen. Disable that in settings.

Decide: live with it, buy gear, or call retention
After 11 steps you know what's actually wrong. Three honest paths:
Pick one
1. The problem was placement or settings. You fixed it for $0. Done.
2. The problem was coverage. Buy a Wi-Fi 6 mesh ($200–$500 once). Return the rental ($14–18/mo killed forever). Net cost over 2 years: usually negative.
3. The problem was your ISP. Call retention. Quote your bill, quote a competitor's offer (always call AT&T Fiber if you're on Spectrum, vice versa). My ISP Negotiation Script walks through the exact two-step. If they won't budge, switch providers — promo pricing for new customers is always lower than your existing rate.
